This book presents excerpts from Swami Vishnudevananda's lectures on all aspects of the immensely broad science of yoga. Swami Vishnudevananda, or Swamiji as he was affectionately named, gave hundreds of lectures to students all over the world. He was an inspiring teacher who, with humor, anecdotes, and stories, made it easy to access even the more complex aspects of yoga.

The lectures were held in the years 1975 to 1990, a time marked by Swamiji's full commitment to the global development of the Sivananda Yoga Vedanta centers, as well as by his personal commitment to world peace. Many lectures were held in the Ashrams and centers of the Sivananda organization, others in public lecture halls, schools and universities. Everywhere people gathered to hear the deep wisdom teachings of yoga. Swamiji's words are timeless and refer directly to the everyday life of modern man.
